    摘要： Optical data storage members in which the guard bands present between data-carrying tracks of conventional data storage members are used to carry information recorded in a manner which avoids the danger of cross-talk between adjacent tracks. One preferred arrangement consists of an optical data storage member comprising an optically recordable surface having a plurality of tracks in which information may be recorded in analogue or digital form, the tracks being of a first type in which the material constituting the track is sensitive to radiation of a first predetermined characteristic and a second type in which the material thereof is sensitive to radiation of a second predetermined characteristic, wherein tracks of the first type alternate across the surface of the second type. The tracks may be constituted by a surface region (1,2,3,4,5) carrying a plurality of closely spaced grooves (11,12,13,14,15), the grooves of one track being orthogonally directed with respect to those of its adjacent tracks. The predetermined radiation characteristic can be the polarization state of the incident radiation.

    摘要： A data storage medium is provided which is suitable for production or replication by moulding, casting, embossing or a similar process against a tool. The data storage medium has a surface or a surface region which is strongly absorbent of at least a predetermined band of wavelengths of electromagnetic radiation. The surface or surface region includes a layer of a heat sensitive material which has a textured surface pattern the pitch of which is smaller than the shortest wavelength of the predetermined band of wavelengths, and the depth (peak-to-trough) of which is at least 100 nm. The surface pattern is free from undercutting, and can comprise an array of protuberances or one or more sets of grooves (which may be intersecting). The textured surface pattern is further coated with a thin film of a high-opacity material, e.g. gold, the thickness of the overcoating preferably being such as to give no more than 10% transmission of incident radiation.A tool for use in producing such a data storage medium, and methods of using the tool, are also disclosed. The data storage medium may be prepared in blank form for use as the consumer desires, or it may be pre-recorded in part or in entirety.

    摘要： Blood flow in a retinal blood vessel is measured by detecting the doppler shift imparted to two laser beams intersecting on a portion of the retinal vessel. Twin beams of laser radiation are directed along an optical path into an eye and scattered radiation returned along the path into two photo-multipliers. The twin beams are passed through a beam rotator so that the plane containing them can be aligned along the retinal vessel under measurement. A local oscillator signal for homodying with the doppler shifted laser radiation is obtained from reflections from the eye itself or a separate reflector. This reflector can be moved to impart a frequency shift to the local oscillator signal to remove ambiguities in the doppler measurements. Automatic tracking of small eye movements is provided by a beam deflector and servo motor controlled by a detector. Width of the retinal vessel under measurement is obtained by deflecting returning scattered laser radiation and determining the width of the detector signal change.
